Stabilizer formalism for generalized concatenated quantum codes [PDF]
2013 IEEE International Symposium on Information Theory, 2013 The concept of generalized concatenated quantum codes (GCQC) provides a systematic way for constructing good quantum codes from short component codes. We introduce a stabilizer formalism for GCQCs, which is achieved by defining quantum coset codes. This formalism offers a new perspective for GCQCs and enables us to derive a lower bound on the code ...

Quantum measurements of atoms using cavity QED
, 2010 Generalized quantum measurements are an important extension of projective or von Neumann measurements, in that they can be used to describe any measurement that can be implemented on a quantum system.

, 2006 Since quantum information is continuous, its handling is sometimes surprisingly harder than the classical counterpart. A typical example is cloning; making a copy of digital information is straightforward but it is not possible exactly for quantum ...

New quantum codes from constacyclic codes over a general non-chain ring
Discrete Mathematics, Algorithms and Applications, 2023 Let [Formula: see text] be a prime power and let [Formula: see text] be a finite non-chain ring, where [Formula: see text], are polynomials, not all linear, which split into distinct linear factors over [Formula: see text]. We characterize constacyclic codes over the ring [Formula: see text] and study quantum codes from these.

Classical -Quantum Multiple Access Channel with Secrecy Constraint: One-shot Rate Region
International Journal of Information and Communication Technology Research, 2020 In this paper, we aim to study a -user quantum multiple access wiretap channel with an arbitrary number of wiretappers under one-shot setting. In this regard, we first introduce the general quantum multiple access wiretap channel and the simplified ...

General Scheme for Perfect Quantum Network Coding with Free Classical Communication
, 2009 This paper considers the problem of efficiently transmitting quantum states through a network. It has been known for some time that without additional assumptions it is impossible to achieve this task perfectly in general -- indeed, it is impossible even

The capacity of hybrid quantum memory [PDF]
, 2002 The general stable quantum memory unit is a hybrid consisting of a classical digit with a quantum digit (qudit) assigned to each classical state. The shape of the memory is the vector of sizes of these qudits, which may differ. We determine when N copies

Distributed quantum dense coding
, 2004 We introduce the notion of distributed quantum dense coding, i.e. the generalization of quantum dense coding to more than one sender and more than one receiver.

Smooth Renyi Entropies and the Quantum Information Spectrum
, 2008 Many of the traditional results in information theory, such as the channel coding theorem or the source coding theorem, are restricted to scenarios where the underlying resources are independent and identically distributed (i.i.d.) over a large number of
